To H (P1710111 III, HUI]; Win") I lie it known that l, Joim E. Timon; a citizen of the United. Status, and rcsiilcnl of Trenton, in the county of l\lcrcor and State of New Jersey. have invented a new and. uscful Head-Adjusting Device, of which the Following is a specification.

My inwntiun relates to a bead, adjusting (lurirc and mom particularly to a device for plai-ing the bead accurately in posiiion on llic tirc whore tho latter is to he subsequcntly (lllekl hctwceu side rings.

In making what is commonly known as: a (llkluillkl tirr. it is common to first build on the core the foundation of Liz; tire. ilnh piac the (-lcmchci' beads in pobition, ihcn cowr tho foundation and chamber ring with outer wrapping-s oi lhc tire and finally presa these clcnchor rings and. the tire zuijar cent; thereto into close contact with tho corn during the proccss of vulcanization. is heconics a matter oil the highest importance to have those beads which form the clencher cilgrs of tho Lire locaicil in exactly the right position throu 'h their entire length in oriirr that the rec/P s: in the: molds v h u" 3 tenilccl to rcccivc them may rcci ivo withoui any .railizii r-rossurc tending to ll plan: than and it to ccoinpl wh this m curate arraiigcm m of the IF ditionsly and erfcc 'ivoly that vcntion is dircch-ili A practical rn'iootli" mom; of my invention is rcpicscinlwl in the. accompanying drawingq, in which Figure l is a sectional View showing film lmaiil adjusting r? lo ihc cor aml lwarLa "Jimum oi tho i l l in an cilgrc rlc'vaiion of live:

The brad is denoted by 3 and is located in i ho shallow curved reccss 4 formwl n the periphery of the bond adjusting ring i The pcriphcry oi the hood adjusting: ring i'" fun tho! prmidccl with av bcWlr-Il portion (3 which is infcmlcd to rest again i the. tire foundation 2 immediately within ihc Posilateral shoulder 8 tho fo mor for rostii'ig against; the tire foundation 2 near the inner edge of the core and the latter to extend within the (ow in close proximity to the inncr wall of the core.

In practica the lira foundation having been laid on the core I, the bead may be laced in position. on the shallow curved recms 1 on the head adjustingring 5 and the latter may thvn be moved laterally into posirii'm with rrs poct to the core 1, the ring itaclf being adjusitcifl accurately in position by the cmrancc of tho shoulder 8 Within the inncr wall of the core and when pressed lam-ally against the tire foundation 2, the hose of rho bead will be brought. into intinialc mi cl, with tho tire foundation 2 undo! such or in will cause the head to ao'hvrc to inc two ilum lation 2 which is commonly formed of unvulcanizcd rubber and the hcad aiijuating ring may then be ren'iovt-il, lowing the oi "ail in its proper position. with reopen. to the core and the tire {Fm-mod ilicrvnn.
